North Pole

Precise definition
See also: Polar motion
The Earth’s axis of rotation and hence the position of the North Pole was commonly believed to be fixed (relative to the surface of the Earth) until, in the 18th century, the mathematician Leonhard Euler predicted that the axis might “wobble” slightly. Around the beginning of the 20th century astronomers noticed a small apparent “variation of latitude,” as determined for a fixed point on Earth from the observation of stars. Part of this variation could be attributed to a wandering of the Pole across the Earth’s surface, by a range of a few meters. The wandering has several periodic components and an irregular component. The component with a period of about 435 days is identified with the 8 month wandering predicted by Euler and is now called the Chandler wobble after its discoverer. The exact point of intersection of the Earth’s axis and the Earth’s surface, at any given moment, is called the “instantaneous pole”, but because of the “wobble” this cannot be used as a definition of a fixed North Pole (or South Pole) when metre-scale precision is required.
It is desirable to tie the system of Earth coordinates (latitude, longitude, and elevations or orography) to fixed landforms. Of course, given plate tectonics and isostasy, there is no system in which all geographic features are fixed. Yet the International Earth Rotation and Reference Systems Service and the International Astronomical Union have defined a framework called the International Terrestrial Reference System.

Pre-1900
As early as the sixteenth century, many eminent people correctly believed that the North Pole was in a sea, which in the nineteenth century was called the Polynia or Open Polar Sea. It was therefore hoped that passage could be found through ice floes at favorable times of the year. Several expeditions set out to find the way, generally with whaling ships, already commonly used in the cold northern latitudes.
One of the earliest expeditions to set out with the explicit intention of reaching the North Pole was that of British naval officer William Edward Parry, who in 1827 reached latitude 8245 North. In 1871 the Polaris expedition, an American attempt on the Pole led by Charles Francis Hall, ended in disaster. An 18791881 expedition commanded by US naval officer George Washington DeLong also ended tragically when their ship, the USS Jeanette, was crushed by ice. Over half the crew, including DeLong, were lost.
Nansen’s ship Fram in the Arctic ice
In April 1895 the Norwegian explorers Fridtjof Nansen and Fredrik Hjalmar Johansen struck out for the Pole on skis after leaving Nansen’s icebound ship Fram. The pair reached latitude 8614 North before they abandoned the attempt and went southwards, eventually reaching Franz Josef Land.
In 1897 Swedish engineer Salomon August Andre and two companions tried to reach the North Pole in the hydrogen balloon rnen (“Eagle”), but were stranded 300 km north of Kvitya, the northeasternmost part of the Svalbard Archipelago, and perished on this lonely island. In 1930 the remains of this expedition were found by the Norwegian Bratvaag Expedition.
The Italian explorer Luigi Amedeo, Duke of the Abruzzi and Captain Umberto Cagni of the Italian Royal Navy (Regia Marina) sailed the converted whaler Stella Polare from Norway in 1899. On March 11, 1900 Cagni led a party over the ice and reached latitude 86 34 on April 25, setting a new record by beating Nansen’s result of 1895 by 35 to 40 kilometres. Cagni barely managed to return back to the camp, remaining there until June 23. On August 16 the Stella Polare left Rudolf Island heading south and the expedition returned to Norway.
19001940
The American explorer Frederick Albert Cook claimed to have reached the North Pole on April 21, 1908 with two Inuit men, Ahwelah and Etukishook, but he was unable to produce convincing proof and his claim is not widely accepted.

The conquest of the North Pole was for many years credited to American Navy engineer Robert Peary, who claimed to have reached the Pole on April 6, 1909, accompanied by American Matthew Henson and four Inuit men named Ootah, Seeglo, Egingwah, and Ooqueah. However, Peary’s claim remains controversial. The party that accompanied Peary on the final stage of the journey included no one who was trained in navigation and could independently confirm his own navigational work, which some claim to have been particularly sloppy as he approached the Pole.
The distances and speeds that Peary claimed to have achieved once the last support party turned back seem incredible to many people, almost three times that which he had accomplished up to that point. Peary’s account of a journey to the Pole and back while traveling along the direct line the only strategy that is consistent with the time constraints that he was facing is contradicted by Henson’s account of tortuous detours to avoid pressure ridges and open leads.
The British explorer Wally Herbert, initially a supporter of Peary, researched Peary’s records in 1989 and concluded that they must have been falsified and that Peary had not reached the Pole. Support for Peary came again in 2005, however, when the British explorer Tom Avery and four companions recreated the outward portion of Peary’s journey with replica wooden sleds and Canadian Eskimo Dog teams, reaching the North Pole in 36 days, 22 hours nearly five hours faster than Peary. Avery writes on his web site that “The admiration and respect which I hold for Robert Peary, Matthew Henson and the four Inuit men who ventured North in 1909, has grown enormously since we set out from Cape Columbia. Having now seen for myself how he travelled across the pack ice, I am more convinced than ever that Peary did indeed discover the North Pole.”
The first claimed flight over the Pole was made on May 9, 1926 by US naval officer Richard E. Byrd and pilot Floyd Bennett in a Fokker tri-motor aircraft. Although verified at the time by the US Navy and a committee of the National Geographic Society, this claim has since been disputed.
The first undisputed sighting of the Pole was on May 12, 1926 by Norwegian explorer Roald Amundsen and his American sponsor Lincoln Ellsworth from the airship Norge. Norge, though Norwegian owned, was designed and piloted by the Italian Umberto Nobile. The flight started from Svalbard and crossed the icecap to Alaska. Nobile, along with several scientists and crew from the Norge, overflew the Pole a second time on May 24, 1928 in the airship Italia. The Italia crashed on its return from the Pole, with the loss of half the crew.
19402000
In May 1945 an RAF Lancaster of the Aries expedition became the first Commonwealth aircraft to overfly the North Geographic and North Magnetic Poles. The plane was piloted by David Cecil McKinley of the Royal Air Force. It carried an 11-man crew, with Kenneth C. Maclure of the Royal Canadian Air Force in charge of all scientific observations. In 2006, Maclure was honoured with a spot in the Canadian Aviation Hall Of Fame.
Discounting Peary’s disputed claim, the first men to set foot at the North Pole were, according to some sources, a Soviet Union party. These are variously described as including Pavel Gordiyenko (or Geordiyenko) and three or five others, or Aleksandr Kuznetsov and 23 others, who landed a plane (or planes) there on April 23, 1948. According to Antarctica.org, three Li-2 planes landed, carrying a total of seven men.
On May 3, 1952, U.S. Air Force Lieutenant Colonel Joseph O. Fletcher and Lieutenant William P. Benedict, along with scientist Albert P. Crary, landed a modified C-47 Skytrain at the North Pole. Some sources consider this (rather than the Soviet mission) to be the first ever landing at the Pole.
USS Skate at the North Pole, 1959
The United States Navy submarine USS Nautilus (SSN-571) crossed the North Pole on August 3, 1958, and on March 17, 1959, the USS Skate (SSN-578) surfaced at the Pole, becoming the first naval vessel to do so.
Setting aside Peary’s claim, the first confirmed surface conquest of the North Pole was that of Ralph Plaisted, Walt Pederson, Gerry Pitzl and Jean Luc Bombardier, who traveled over the ice by snowmobile and arrived on April 19, 1968. The United States Air Force independently confirmed their position.
On April 6, 1969, Wally Herbert and companions Allan Gill, Roy Koerner and Kenneth Hedges of the British Trans-Arctic Expedition became the first men to reach the North Pole on foot (albeit with the aid of dog teams and air drops). They continued on to complete the first surface crossing of the Arctic Ocean and by its longest axis, Barrow, Alaska to Svalbard a feat that has never been repeated. Because of suggestions of Plaisted’s use of air transport, some sources classify Herbert’s expedition as the first confirmed to reach the North Pole over the ice surface by any means.
Memorial in honor of icebreaker Arktika conquest of the North Pole in 1977 in hall of museum of local lore of the Murmansk region
On August 17, 1977, the Soviet nuclear powered icebreaker Arktika completed the first surface vessel journey to the North Pole.
In 1982 Sir Ranulph Fiennes and Charles Burton became the first people to cross the Arctic Ocean in a single season. They departed from Cape Crozier, Ellesmere Island, on 17 February 1982 and arrived at the geographic North Pole on 10 April 1982. They travelled on foot and skidoo. From the Pole, they travelled south towards Svalbard but, due to the unstable nature of the ice, ended their crossing at the ice edge after drifting south on an ice floe for 99 days.
